Aplicação da metodologia de superfície de resposta na remediação de um solo arenoso contaminado artificialmente com cobre

Soil flushing is an alternative remediation technology for soils contaminated with heavy metals, which the main contaminant removing process consists in percolating an extraction solution. This work aimed to use the response surface methodology to point out combinations among the parameters of the extraction solution (Na2EDTA concentration, volume e pH) in order to reduce the concentration of copper in a sandy soil to risk levels lower than the intervention levels for exposure scenarios adopted by the Environmental Company of Sao Paulo State. Thus, a series of tests in leaching columns were carried out using a Fluvisol artificially contaminated (1257,3 mg kg-1). The tests were conducted in triplicate and setup a central composite rotatable design with 15 different parameters combinations of the extraction solution and one replicate in the center point. Using 5% significance level, the adjusted model (R2 = 0,98) indicated combinations of Na2EDTA concentration, pH and volume of the extraction solution which allow reduction of copper concentration below levels reported by environmental agency of Sao Paulo State for industrial, residential, agricultural or maximum exposure scenarios.

Diversidade genética e eficiência de DNA microssatélites para o controle genealógico da raça Nelore

Foram estimados na raça Nelore a variabilidade genética e os valores de determinação de paternidade usando-se 11 marcadores microssatélites do painel ISAG/FAO. Estes foram organizados em quatro conjuntos de amplificação para genotipagem semi-automática por fluorescência. Todos os marcadores apresentaram-se altamente polimórficos, com média de 8,2 alelos por loco. A heterozigosidade observada, com média de 0,48, foi menor que a esperada em 10 locos. Foram observadas deficiências de heterozigotos em nove locos, o que resultou no desequilíbrio de Hardy-Weinberg para a população estudada. O conteúdo polimórfico informativo foi superior a 0,5 em 10 locos. O poder de discriminação foi >0,999 e as probabilidades de exclusão de paternidade quando são conhecidos os genótipos de um bezerro, sua mãe e um pai alegado, ou quando um ou outro genótipo parental não está disponível, para o conjunto de marcadores foram >0,999 e >0,989, respectivamente. O conjunto de 11 marcadores constitui método eficiente para a determinação de paternidade na raça Nelore.

Using Slaughter Weight to Predict Weight and Yield of Primal Cuts of Carcass from Buffaloes

The knowledge of the meat production from different buffalo breeds and their crossings in different feeding systems becomes necessary for the supply of subsidies to whole productive meat chain. Some quantitative carcass traits of Mediterranean buffaloes bulls, finished in feedlot, with initial age of fourteen months and 330 kg live weight, slaughtered with 450, 480, 510 and 540 kg, were evaluated. The diet contained 13% crude protein, 2.68 Mcal digestible energy/kg DM and a roughage : concentrate ratio of 25:75. Regression equations for prediction weight and yield of primal cuts of carcass as a function of slaughter weight were obtained. Carcass dressing percent increased as the slaughter weight increased (49.2; 49.5; 49.7; and 49.9%). The Pistola Style cut weight although increasing linearly in weight (108.2; 117.6; 124.0 and 130.7 kg) as the slaughter weight increased, declined linearly when expressed in relation to cold carcass weight (49.5; 49.0; 48.6 and 48.2%). In this experimental conditions Mediterranean young bulls slaughtered between 450 to 540 kg of live weight showed increasing yields of cold carcass, forequarter and thin flank.

Figuras da comédia em prosa

El ilustrador francés Jacques Callot (1592-1635) representó personajes de la Commedia dell’Arte en su obra Balli di Sfessania (1616-1620), compuesta por 24 figuras. Esas imágenes se caracterizan por mostrar personajes en movimiento, teniendo al fondo escenas de la realidad italiana. El romántico alemán E. T. A. Hoffmann (1776-1822) insirió en sus cuentos y romances muchos elementos que remiten a las obras tanto de otros escritores como de pintores y músicos. Callot fue visitado por por Hoffmann en varias de sus publicaciones, entre ellas el cuento “Princesa Brambilla” (1821),que posee ocho imágenes directamente elaboradas a partir del modelo de Callot en Balli di Sfessania. Esas imágenes, sin embargo, no representan meras “ilustraciones” con respecto a la historia. Mucho más que ello, las imágenes demuestran como Hoffmann interpretaba las figuras de Callot y, como ellas sintetizaron la relación del escritor con Italia ( país que siempre deseó, pero nunca logró visitarlo) y con el arte pictórica.

Using SPE-LC-ESI-MS/MS analysis to assess disperse dyes in environmental water samples

We have optimized an SPE-LC-ESI-MS/MS method and used it to monitor disperse azo dyes in environmental aquatic samples. Calibration curves constructed for nine disperse dyes-Red 1, Violet 93, Blue 373, Orange 1, Orange 3, Orange 25, Yellow 3, Yellow 7 and Red 13-in aqueous solution presented good linearity between 2.0 and 100.0 ng mL(-1). The method provided limits of detection and quantification around 2.0 and 8.0 ng L(-1), respectively. For dyes at concentrations of 25.0 ng mL(-1), the intra- and interday analyses afforded relative standard deviation lower than 6 and 13%, respectively. The recovery values obtained for each target analyte in Milli-Q water, receiving waters and treated water samples spiked with the nine studied dyes at concentrations of 8.0, 25.0 and 50.0 ng L(-1) (n = 3) gave average recoveries greater than 70%, with RSD <20%. Statistical evaluation aided method validation. The validated method proved to be useful for analysis of organic extracts from effluents and receiving water samples after an SPE extraction step. More specifically, the method enabled detection of the dyes Disperse Red 1, Disperse Blue 373 and Disperse Violet 93 at concentrations ranging from 84 to 3452 ng L(-1) in the treated effluent (TE), affluent and points collected upstream and downstream of the drinking water treatment plant of a textile dye industry in Brazil.
